TLDR
A flow body flow meter as discussed by the authors includes a flow body and a sensor having one or more probes in the flow body, where the sensors of the sensor are located in a part of the rotating flow that is free of any liquid phase particles.
Abstract
A flow body flow meter includes a flow body and a sensor having one or more probes in the flow body. As a wet gas stream enters the flow body, an internal passage imparts angular momentum to the stream to induce a rotating flow. The wet gas stream at least intermittently carries liquid phase particles and the inertia of the denser liquid phase particles separates them from the rotating flow. The probes of the sensor are located in a part of the rotating flow that is free of any liquid phase particles. The internal passage may include an axial swirler and a cylindrical section downstream from the axial swirler. The axial swirler imparts the nonlinear motion to the stream, and tips of the probes are located near a center axis of the cylindrical section so they are free of any liquid phase particles.

Flowmeter with flow conditioner

TL;DR: In this paper, the authors describe flow path features for improving the measurement accuracy or other aspects of the flowmeter, such as a conditioning section with diametrically opposed longitudinal rib protrusions, which can reduce swirling flow, direct liquid components of a multi-phase flow towards the sidewalls of a flow path, and guide ballistic particles through the center of flow path away from sensitive measurement devices.

Systems and Methods for Thermal Imaging Technique for Measuring Mixing of Fluids

TL;DR: In this paper, a method for measuring mixing of gaseous fluids using thermal imaging comprises: positioning a thermal test medium parallel to a direction gasesous fluid flow from an outlet vent of a momentum source, wherein when the source is operating, the fluid flows across a surface of the medium, obtaining an ambient temperature value from a baseline thermal image of the surface, and calculating at least one temperature-difference fraction associated with at least a first position on the surface.

Method for determining flow regime in multiphase fluid flow in a wellbore

TL;DR: In this article, the authors proposed a method of determining the flow regime of fluid having more than one phase flowing in a conduit, which includes the step of positioning a sensor in the conduit, the sensor generating measurements capable of discriminating more than 1 phase in the fluids, generating measurements from the sensor for a period of time, characterizing the measurements with respect to changes in magnitude of the measurements occurring during the period, and comparing the characterized measurements to similarly characterized measurements of a similar sensor positioned within flow streams having known flow regimes.
